Upright extracton cleaning machine with handle mounting
First Claim
1. A portable surface cleaning apparatus, comprising:
- a base module for movement along a surface and comprising a base housing having a rear portion;
the base housing including an upper housing portion and a lower housing portion which have arcuate surfaces that between them define a socket;
an upright handle having depending arms spanning the base housing, the arms having inner and outer sides, with the inner sides being adjacent the base housing, the inner sides of the arms having bearings which are rotatably received in the socket defined by the arcuate surface of the upper and lower housing portions, for pivotally mounting the handle to the base housing;
a fluid recovery system comprising;
a tank having a fluid recovery chamber for holding recovered fluid;
a suction nozzle associated with the base module;
a working air conduit extending between the recovery chamber and the suction nozzle;
a vacuum source in fluid communication with the recovery chamber for generating a flow of working air from the nozzle through the working air conduit and through the recovery chamber to thereby draw dirty liquid from the surface to be cleaned through the nozzle and working air conduit, and into the recovery chamber; and
a liquid dispensing system comprising;
a liquid dispensing nozzle associated with the base module for applying liquid to a surface to be cleaned;
a fluid supply chamber for holding a predetermined amount of supply fluid; and
a fluid supply conduit fluidly connected to the fluid supply chamber and to the dispensing nozzle for supplying liquid to the dispensing nozzle.

Abstract
A portable surface cleaning apparatus including a base module for movement along a surface, an upright handle pivotally attached to the base module, a liquid dispensing system including a fluid supply chamber in the form of a bladder for holding a supply of cleaning fluid, a fluid recovery system including a tank on the base module having a fluid recovery chamber for holding recovered fluid and housing the flexible bladder, wherein the recovery chamber is in fluid communication with the fluid supply chamber and the pressure in the flexible bladder is equalized with the pressure in the tank as the cleaning fluid is dispensed from the supply chamber and the dirty liquid is collected in the recovery chamber. The base module includes upper and lower housing portions and the upright handle is pivotably mounted to the base module through at least one bearing for rotatable reception in the housing.
